Rule 4 of the Racing Rules of Sailing states: "The responsibility for a boat's decision to participate in a race or to continue racing is hers alone." 

Sailing is by its nature an unpredictable sport and therefore inherently involves an element of risk. By taking part in the event, each competitor agrees and acknowledges that:

(a)        They are aware of the inherent element of risk involved in the sport and accept responsibility for the exposure of themselves, their crew and their boat to such inherent risk whilst taking part in the event;

(b)        They are responsible for the safety of themselves, their crew, their boat and their other property whether afloat or ashore;

(c)         They accept responsibility for any injury, damage or loss to the extent caused by their own actions or omissions;

(d)        Their boat is in good order, equipped to sail in the event and they are fit to participate;

(e)        The provision of a race management team, patrol boats and other officials and volunteers by the event organiser does not relieve them of their own responsibilities

(f)         The provision of patrol boat cover is limited to such assistance, particularly in extreme weather conditions, as can be practically provided in the circumstances;

(g)        It is their responsibility to familiarise themselves with any risks specific to this venue or this event drawn to their attention in any rules and information produced for the venue or event and to attend any safety briefing held for the event;

(h)        They are responsible for ensuring that their boat is equipped and seaworthy so as to be able to face extremes of weather; that there is a crew sufficient in number, experience and fitness to withstand such weather; and that the safety equipment is properly maintained, stowed and in date and is familiar to the crew.
